Both of ours have had paint protection. I take them to a hand car wash, run by two brothers who are brilliant. They wash the cars exactly the same way I do, and take pride in what they do. There is always a queue, even though they are not the cheapest (or only one around). On average, there is a wait around 45 minutes to an hour before I get to the front of the queue. One brother washes, the other drys. Either I wash my cars or they do. I won't even let the Dealer do it.
